POLISHING-TOOL.

SPECIFICATION forming part of Letters Patent No. 779,186, dated January 3, 1905.

Application filed February 10, 1904; Serial No- 192,931.

To ctZZ 1079/0771; it may concern:

Be it known that 1, CHARLES A. L. SAUN- DEBS, a citizen of the United States, and a resident of Elgin, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Polishing-Tools, of which the following is a description.

My invention belongs to that class of devices intended for use in polishing or finishing the surfaces of different kinds of material, and is particularly adapted for use in polishing the shanks and soles of shoes as they are finished at the factory.

The object of my invention is to provide a simple and effective device for the purpose described which shall also be particularly adapted for, working into angles or cornersfor example, such as at the point where the heel joins the sole of a shoe.

To this end my invention consists in the novel construction,arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference-figures indicate like or corresponding parts, Fig ure 1 represents the preferred form of my invention. Fig. 2 is a longitudinal section of thesame on line 2 2 of Fig. 1. Fig. 3 is a face view of the polishing-head. Fig. 4L is asection on line 4 4 of Fig. 1. Fig. 5 is a modified form in which polishing-head is solid, parts being broken away to show the construction; and Fig. 6 shows my invention as applied to a flexible shaft.

In the drawings, 1 is a suitable shaft provided with any preferred means for rotating the same for example, by the belt-pulley 2 (shown in Fig. 1) or equivalent means.

3 is a substantially mushroom-shaped polishing-head provided with ashort shaft 4, adapted to be positioned in and secured to the rotating shaft in any preferred manner for example, by the set-screw 5. The exterior surface or outer end of the polishing-head is provided with a plurality of indented lines, grooves, or channels 6, extending from the circumference inward, the marginal edges of said indentations being dulled or rounded to form polishing means and prevent tearing the Work. In

the preferred form (shown in Fig. 3) one and 5 preferably two of the sections of the polishing-faces thus divided by the lines 6 extend past the center of the face to avoid as far as possible the pitting or similar marking of the surface polished by reason of the operation of 5 5 the central part of the device. As will be seen, the exterior surface of the head forms the polishing-face of the head and is arranged transversely to or at substantially right angles to the axis of rotation of the same, and the face is also preferably crowned to aid in working the tool in the depressions and similar points difiicult to reach by a straight-faced tool.

The polishing-head may be a solid block, as 5 shown in Figs. 5 and 6, provided with the depressed or indented lines 6 6; but in the preferred form the head is formed of a plurality of independently-movable sections 7, whose outline or marginal edges form the primary 7 polishing means before referred to. The forms of these various sections may be varied as desired. The several sections are assembled to form a complete head and are resiliently maintained at their outward limit by any preferred means. As clearly shown in Figs. 2 and 1, this may be practically accomplished by forming the shanks of the several sections with slots 8 engaging pins 9, carried by the shaft or central core 4E of the head. Helical springs 10 or equivalent means are positioned between the inner ends of the several sections and a collar 11, which is in turn firmly secured to a sleeve 12, retaining the several sections in proper relative posi- 5 tion. It will be obvious that in the use of this form of my improved device each section will be resiliently yieldingand independently movable and that each section is complemental to the others, which together form a complete 9 head.

In practice my device has been found very effective in polishing the soles and shanks of shoes, for which it is particularly adapted; but it is obvious that it may be employed for other polishing purposes. Consequently I donot wish to be understood as limiting myself to that single use. It is also obvious that the forms of the several sections or the location and arrangement of the indented lines 6 may be varied as preferred.

In practice I have found the form illustrated to be very effective and prefer ,an arrangement substantially as shown. While I consider the solid head, as shown in Fig. 5, in ferior in its operation, yet it is adapted for effective service and operates very satisfactorily upon certain classes of work.

It is obvious that the shaft 1 may be firmly maintained in suitable hearings in a fixed position and the work held to the polishinghead, as shown in Figs. 1, 2, and 5, or, on the other hand, the work may be maintained in a fixed position and the head secured to a flexible shaft 13, as shown in Fig. 6, or equivalent rotative means. In the latter form a suitable handle 14 is provided for the manipulation of the tool.

Having thus described my improvement, it is obvious that immaterial modifications may be made without departing from the spirit of my invention. Hence I do not wish to be understood as limiting myself to the exact form and arrangement shown.

By the word polishing-line in the description and claims of this application I wish to be understood as meaning polishing means consisting of the edges of indented grooves or the obviously reverse construction having fihesame ofiice and function in a device of this Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A polishing-tool comprising a rotatable mushroomeshaped head having its outer end provided with a plurality of grooves or channels the marginal edges of which form polishing means, one or more of said grooves or channels being extended substantially to the center of the face whereby the entire outer end of the head forms a polishing-surface.

2. A polishing-tool comprising a rotatable mushroom-shaped head having its outer end formed with a plurality of grooves or channels extending inwardly from its circumference dividing the face into a plurality of sections, the marginal edges of which form polishing means, one or more of said sections being extended past the center of the head.

3. In a polishing-tool, a rotatable head COHI.

prising a plurality of resiliently-yielding and independently movable complemental sections,suitably retained in proper relation to one another, each section having its edges dulled and constructed to serve as polishingdines, the working face of the head arranged transversely to its axis of rotation; substantially as described.

4. In apolishing-tool, arotatable head comprising a plurality of resiliently-yielding and independentlymovable complemental sections, suitably retained in proper relation to one another and formed to produce a crowning head, each of said sections having its edges dulled or rounded to serve as polishing-lines, the working face of the head being arranged transversely to its axis of rotation; substantially as described.

5. In a polishing-tool, a rotatable head comprising a plurality of resiliently-yielding and independently-movable complemental sec' tions, suitably retained in pro per relation to one another, one or more of said sections extending inward past the center of the head, substantially as described, the marginal edges of said sections being dulled and constructed to serve as polishing-lines, and the working face of the head being arranged transversely to its axis of rotation; substantially as described.

6. In a polishing-tool, a rotatable head comprising a plurality of complemental sections each provided with an extending shank having formed therein aslot 8, ashaft L provided with a plurality of pins 9 positioned within said slot, the several sections being formed to embrace the shaft to form a complete polishing-head, in combination with a sleeve embracing the several shanks to maintain the several sections in proper relative position, and resilient means for normally maintaining the several sections at their outer limit; substantially as described.

7. In a polishing-tool, a rotatable head comprising a plurality of complemental sections each provided with an extension the several extensions being grouped to embrace the shaft to position the sections in proper relative position, each of said sections being provided with a slot 8, in combination with a shaft 4 provided with a plurality of pins 9 located within said slot 8, an embracing sleeve 12 loosely inclosing the said extensions and maintaining the sections in proper relative positions, and springs arranged between the inner ends of the extension, and a relatively fixed part of the device, whereby the several sections are normally maintained at their outer limit; substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
